Problems with Soulseek search

Hello.
I am having some strange problems with Soulseek search like for example in order to find the song Advocado, Baby by Los Campesinos I try "campesinos advocado" and find nothing. But if I look for just "Campesinos" and look all the list then the music is there. Also, if I look for "Advocado" it doesn't return the correct song, just some others, even though the song is there. This sort of thing have happened to many songs. I am using the 2013.11.6 version.
Can anybody help?
Thanks!

Song is "Avocado, Baby", not "Advocado, Baby". That's why.
